Product Overview
The WZPK-233S armored platinum resistance thermometer utilizes imported platinum resistance elements as its core temperature-sensing component, delivering high-precision temperature measurement for industrial applications. With a compact diameter, excellent flexibility, and superior vibration resistance, this product is ideal for installations where conventional assembled platinum resistors cannot fit. Its stainless steel sheath, filled with high-density oxide insulation, ensures robust performance in harsh environments by combining contamination resistance with mechanical durability. The operating range spans from -200°C to 500°C, and it connects directly to secondary instruments via copper wires, providing reliable temperature signals for displays, recorders, and controllers.
Featuring a modular design, the product includes a sensing element, protective sheath, junction box, and multiple mounting options, with single or dual-element configurations (dual-element models output two synchronized signals). The junction box offers waterproof variants for diverse installation conditions, while fixation methods such as threaded or flanged mounts enable versatile deployment. The platinum element leverages the resistance-temperature characteristics of platinum wire for accurate measurements, supported by structural optimizations that enhance long-term stability and repeatability. 151724
技術(shù)優(yōu)勢(shì)
WZPK-233S在熱響應(yīng)時(shí)間、絕緣性能及兼容性方面表現(xiàn)突出。其熱響應(yīng)時(shí)間（t0.5）指溫度階躍變化時(shí)輸出達(dá)到50%所需時(shí)間，優(yōu)化設(shè)計(jì)顯著提升了動(dòng)態(tài)響應(yīng)速度。常溫絕緣電阻值不低于100MΩ（測(cè)試電壓10～100VDC），保障了信號(hào)傳輸?shù)姆�(wěn)定性。產(chǎn)品允許最大測(cè)量電流為5mA，避免過(guò)熱影響精度。保護(hù)管材料采用1Cr18Ni9Ti不銹鋼，兼顧耐腐蝕與承壓需求，公稱壓力測(cè)試為1.5倍常規(guī)值，確保結(jié)構(gòu)安全。
針對(duì)流動(dòng)氣體或液體測(cè)量場(chǎng)景，可選帶固定螺栓接頭的型號(hào)（如WZPK-233S），減少介質(zhì)沖擊影響。雙支型號(hào)采用三線制引線，有效抵消導(dǎo)線電阻誤差，適合高精度應(yīng)用。用戶可根據(jù)實(shí)際需求選擇不同外徑（如φ3mm～φ6mm）和插入深度，適配管道或設(shè)備空間限制。3712
Technical Advantages
The WZPK-233S excels in thermal response time, insulation performance, and compatibility. Its thermal response time (t0.5) — the duration required to reach 50% output after a temperature step change — is minimized through optimized design for rapid dynamic response. With a minimum insulation resistance of 100MΩ (tested at 10–100VDC), the product ensures stable signal transmission. The maximum measuring current is limited to 5mA to prevent accuracy degradation from self-heating. The 1Cr18Ni9Ti stainless steel sheath balances corrosion resistance and pressure tolerance, with a nominal pressure test of 1.5× rated value for structural integrity.
For measuring flowing gases or liquids, models with fixed bolt connections (e.g., WZPK-233S) mitigate medium impact. Dual-element versions employ a 3-wire lead configuration to cancel lead resistance errors, ideal for high-precision applications. Customizable outer diameters (e.g., φ3mm–φ6mm) and insertion depths accommodate spatial constraints in pipelines or equipment. 152428
